UNITED STATES PATENT. OFFICE.

Application filed January 18, 1921. Serial No. 488,180.

To all whom it may concern:

Be it known that I, HOMER E. GILLAND, citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Locks, of which the following is a specification.

This invention relates to looks for automobiles and has for an object the provision of means for locking the hood of a vehicle against unauthorized opening when the engine is not running or when the vehicle is left unattended.

Another object of the invention is the provision of a lock for this purpose which is controlled by the ignition circuit of the en ine, so that when the circuit is broken an the engine idle, the hood will be locked and tampering with the mechanism beneath the hood revented.

Other 9 jects and advantages of the invention will appear as the following description is read in connection with the accompanying drawings.

In the drawings Figure 1 is a fragmentary section through a portion of the frame and hood of an automobile with the invention applied.

Figure 2 is an enlarged vertical section throu h the lock and hasp, showing the same in loo ed position.

Fi 3 is a similar View with the parts in unloc ed position.

Fig. 4. is a rear elevation of.the lock.

Figure 5 is a detail elevation of the hasp.

Fig. 6 is a front elevation of a modified form of the invention.

Referring to the drawings in detail, wherein like characters of reference denote col-res onding parts, the reference character 10 in icates a stationary portion of the vehicle structure, such as one of the side members of the frame and 11 one of the hin ed sides of the hood.

.T e invention which is designed to'be secured to a stationary portion of the vehicle comprises a casing 12, having a chamber 13 and oppositely extending outwardly disposed apertured cars 14 which provide means for securin the casing in position. The casing is further provided with a slot 16, which is designed to receive a right angled extension 17 of a hasp 18. This hasp is secured'to the hood through the medium of suitable fastening devices which pass through openings 19. while extension 17 is provided with an opening 20.

Located within the chamber 13 is an electromagnet 21, the latter being secured in position by means of a bracket 22 and being included in the ignition circuit of the engine, part of said circuit being indicated at 23.

The upper end of the casing 12 is provided with parallel openings 24 and 25 and mounted for sliding movement in these openin are the parallel legs of a U-shaped shack e 26. One leg of this shackle o crates within the opening 24. and is norma ly ur ed u ward by means of a coiled spring 2%. e other leg of the shackle is shorter than the first mentioned leg and operates in the opening 25 and its extremity is beveled as indicated at 26. This extremity normally pro jects into the slot 16 so that the hasp 18 may be inserted in this slot and during such insertion will depress the shackle against the action of the spring 27 until the opening 20 registers with the opening 25, whereupon the spring will force the short arm of the shackle into the opening 20 when the parts will be in locked position.

The shackle 26 has secured thereto an armature 28 and when the ignition circuit is completed to start the engine the magnet 21 will be energized and the armature attracted. This will draw the shackle downward and disengage its arm from the hasp 18 and permit the hood to be opened. One or more of these locks may be applied upon opposite sides of the hood as desired.

In Figure 6 there is illustrated a modified form of the invention in which the shackle is controlled by an ordinary spring lock 29, operated by a'suitable key, the openin for which is indicated by the numera 30. Passing through the plate 21 which is provided with attaching ears 32, there is a lock casing 33 which houses the lock for operating the shackle 34 which passes through slots from the upper part of the casing. This slotted portion of the casing is identical to the construction of the preferred form.

The invention is susceptible of various chan es in its form, roportions and minor 'detai s of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed 1s:

The combination of a motor driven vehicle and the hood thereof, of a casing suitably secured to a stationary portion of the motor vehicle in juxta-position to the side edge of the hood and being rovided with a chamber and having a s 0t arranged directly above the chamber and in communication therewith by means of a pair of parallel openings, an apertured has carried by the slde edges of the hood and being adapted to be recelved in the slot with one of its apertures registering with an opening in the casin a U-shaped spring pressed shackle slidab 3 mounted in the openin s of the casing an means secured in the member for influencing the movement of the shackle as and for the purpose specified.

In testimony whereof I aflix my signature.

HOMER E. GILLAND.
